Hi all,
I'm looking for how to access list items in a reasoner rule. E.g the pattern
(?S owl:kasKey ?L) returns a list of all matching objects. Is there any way to
access here the elements of the list for further processing, e.g. to print them
all out?
Thanks

Hi all,
I would like to ask you a few questions about Jena.
I read in the documentation that
*Note:* Although OWL version 1.1 is now a W3C recommendation, Jena's
support for OWL 1.1 features is limited

from the OWL 1.1
The issue was an annotation library that was resetting the class returned
by TypeMapper for xsd:string. Fixing the annotation library solved the
problem.

Hello,
I have been working with Fuseki and TDB for quite some time, however this
weekend I have been trying to setup Fuseki with SDB. In particular, I have my
application to open a connection to a local MySQL server and then to create a
new database called sdb_data. Then I create a Store
Hi,
In answer to your questions:
- Fuseki build 0.2.7
- Yes the strack trace was from the client, no errors visible from the server
- OS is Windows, with client and Fuseki running on the same machine.
I worked around this issue by introducing a small sleep between
inserts as you also suggested.
Thanks, Olivier: that did the trick!
I tweaked it slightly as not all objects have a rdfs:label populated,
and I need to keep that restriction. But using this query the maximum
execution time drops to around 700ms:
SELECT DISTINCT * WHERE {
{ SELECT ?object ?label ?accessionNumber WHERE
The syntax for inserting a blank node requires a _: as the scheme I.e.
INSERT DATA { _:ID http://pred value }
Otherwise you have just used a relative URI and the server resolves it
against a default base URI of http://example/update-base
Hope this helps,
Rob

Yes that more common case you've identified would be affected so switching
this optimizer off until we've resolved this is the way to go

I have no idea of the performances drop if you add that requirement.

There is even a fast front end cache for SPARQL
https://svn.apache.org/repos/asf/jena/Experimental/sparql-cache/
that executes the query once then uses the precomputed results for
LIMIT/OFFSET. It preserves the order so you get pseudo-paging.
But this code is not part of the release and
